A VR simulation game that everyone is trapped in. The contestants have to kill each other to survive. And they don't remember how or who put them in that world. The only option that is used the most is suicide attempts. But also, to win, you have to kill a person without getting caught. The main character wants to stop this from happening and to beat the Alpha leader. Everyone wears masks in this simulation and if they remove it, they die. One person dies before the game starts as a sacrifice. Everyone gets four lives. If they are wasted, they are eliminated.
